TYPE-WRITING MACHINE;

To all whom it mayconcern: 1

Beit known that I, JOHN J CHAPIma citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented. certain new and useful Improvements in TypeWri'ting Machines, of which the followingis a specificatio The present invention relates to mechanism in a typewriting machine for variously controlling the laterally shiftable paper car riage and one object is to provide proved tabulator arrangement in which depression'of a single key will cause the carl'S-riage to move to a columnar position pre determined by the setting of a stop, such key being automatically locked in operative position so that completion of thetabnlating operation will not depend upon continued depression of the key by the operator and at the same time provision is made for prevent-' iug the tabulating devices taking effect until the keyv has been fully depressed. F urthermore, such key will be automatically released when the carriage has arrived at the proper position, repeated depression of the key being then permissible 'to cause a repetition of the tabulating operation.

'A- further object of the invention is to provide for effectively braking the carriage in its tabulating movements, provision being made in this connection for an increase in the braking effect as the carriage gains headway. l A still further object is to provide for rendering effective a keyboard look by depression of the tabulator key so that no type can be struck while the tabulator key is in use.

The invention furthermore includes improvements in margin and end stop devices as well as tabulator stop devices, designed to facilitate manipulation for securing the various results in control of the paper carriage and the general use of the machine.

lVith these and incidental objects in view theinventiou consists in certain novel features of construction and combinations of parts. the essential elements whereof are recited in the appended claims and a preferred form of embodiinent of which is described in detail hereinafter and fully illustrated in Specification of Letters Patent.

In the drawings the reference numeral '2 generallv designates the supporting framework of the machine: 3 the character ke v levers which will be appropriatelv connected with type'bars which in the present instance operate on the. so-called t'ront strike principle: the centering guide being designated by the numeral. 4. a ribbon vibrator by the numeral 5 and .the ribbon spools by the roller 17 loose on the sleeve.

of the escapement rack overlies said roller. and it will be obvious that turning of the rock'shaft'to lift" the arm 13-will have the tabulating purposes the rack 9 will be lifted 'out of engagement with the escapement pinion 1,1. This is effected through the medium of a radial arm 13 secured to a rock shaft ll journaled in bearings at the back of the supporting framework, said arm 13 having a journal stud 15 screwed in its end (Fig. 10). a sleeve 16 loose on said stud and A flange 18 effect of raising the rack out of engagement with the escapement pinion.

The rock shaft H has secured toit near the righthand'end an angular arm 19 a de pending part of which terminates in alaterally bent portion 20 through which loosely passes a screw 21 (Fig. 2), said screw carrying a thumb nut 22 on thelower side of said laterally turned portion of the arm and notched to engage a projection on the latter for locking purposes. Said scr'ew at its upper end "holds one extremity ,of a spiral spring 23, the opposite end of which is attached'to an arm 24; loose on the rock shaft 14 and notched for engagement of a stud '19 on the arm 19. llhe forward end of said arm 24 is coupled to a depending link 25 which at its lower end is pivotally connected with a lever 26 pivoted intermediate its ends at 27 to a tabulator key lever 28. The latter is pivotallv mounted intcrn'iediate its ends as at 29 on the framework of the machine and at its forward end carries a tabulatorkey 30 (Fig. 1). A spring 31 connects the for ward end of the lever 26 with a stud onthe framework and said lever 26 in rear of its pivot underlies a stud 32 on the lever 28 so that the spring 31 normallv operates to depress the rear portion of the tahu'lator key leve and elevate its front portion. A latch,

pivoted at 34 to the framework and drawn ,reaiwardly by a spring 35 normally restrains the lever 26in" engaging over a stud Sit proiectin; laterally from said lever in rear of its pivot (Fig. 2l. Consequently when the tahulator key is first depressed the rear end of the lever 26 will not move up withv the rear portion of the tabulator key lever but said lever 26 will assume the posi tion indicated indotted lines in Fig. 8-. The latch is formed on its rear side at-a point 'below the shoulder which engages tjhe' stud 36,-w1th acarn rise or. pro ection 37 and the merger? lever 28 at its rear end has a depending portion 38 with a laterally projecting stud 39 at the lower extremity, adapted as the tabulator key lever completes its movement under depression of the tabulator key to act upon said cam rise and displace the latch, releasing the lever 26. Thereupon the spring 31 whose tension has been considerably increased by reason of the detention of the lever 26, will rock said lever to the position shown in full lines in Fig. 3, lifting the arm 24- through the medium ofthe link 25 and said arm 24 through the medium of the spring 23 lifts the arm 19. rocking the shaft 1% and raising the arm 13 which lifts the escapement rack out of engagement with the escapement pinion.

On the rear bar of the carriage frame there is secured a lug Obeveled on the right hand side and squared off on theleft hand side, the latter adapted to cooperate with the adjustable stop devices presently to be described. for properly locating the carriage at; r

the desired columnar position when the escapement rack is released as above described.

A tabulator bar 41 square in cross section is mounted to rock in hearings in the main framework, also being longitudinally movable to a limited extent in its bearings. Said bar is marked with a scale on its top side and a similar scale on its front side and is channeled longitudinally in its rear side as illustrated in Fig. f and notched from end to end above and below the channel as shown at 42. {hi this tabulator bar there are permanently arranged any desired number of slidingly adjustable stop devices. As they are duplicates of each other a descriptionof one will sutlice for all. The stop device comprises a body portion 43 channeled to embrace the under and front and rear sides of the bar and having a cap plate 44 extending over the 'top of said bar. This cap plate is open in the center as-at 45 to expose marks on the top scale of the bar and is marked for registry with said scale. The front of the body portion 43 is also open as.

shown at 46 to expose the scale on thefront side of the bar and the front edge of the body portion which comes flush With the front side' of the bar is marked for registry with said scale, see "Fig. 6. There projects from the body portion 48 above the opening 46 a square lug 47 for the lug to on the carriage to abut. T he hody portion -13 in rear of the bar is bored to accommodate a sliding dog l8 having a stem 49 sliding through an opening in the cap plate 4t. Said. dog is formed on flattened front surface with sg'iaced pairs of teeth 50- (Fig: 7) to engage the notches of the bar 41., An inverted cup" shaped knob ta is screwed to the end of the stern -l9 and. a spi spring 4C8 surrounds the latter within. said knob normally elevate ing the dog to'engazge T the notches of the tabulator bar as shown in Fig.

5. Pressure on the knob 49 will disengage said teeth from said notches so that the up- .gaging the escapement rack .from the es-' capement pinion as already described but.

per set of teeth-will be moved into the channel of the tabulator bar and the lower setof teeth will be carried below said channel when the stop piece can be slid along the tabulator bar and located at any point de sired.

The-tabulator bar normally maintains an angular position in which the lug 47 of the stoppiece is above the plane of movement of the lug 40 on the carriage so that the latter. lug will freely'pass in ordinary writing operations of the machine. Depression of the-tabulator key not only results in disenalso has the effect of rocking the tabulator bar to bring the stop lug in the path of the carriage lug. For this purpose there is secured to the left-hand end of the tabulator bar a plate 51 bifurcated in its lower edge to 53 swings rearward and through the medium of the spring 51 rocks the tabulator bar so as to bring the stop lug in the line of the carriage lug.

A spiral spring 60 seated in a recess ofthe framework surrounding the, left hand journal of the tabulator bar bears against the plate 51., tending to thrust said bar to the right. butis' normally restrained from so doing by a lever 61 pivoted intermediate its ends to a lug of the framework as at 63, bifurcated at its upper end to engage a circumferential groove (it in the tabulator bar (Fig. t) and normally engaged at its lower end'with the right hand side of,an angular rearward extension 24'. of the before-mentioned arm 24 which is fast on the rock shaft 14. It is obvious that the spring .60 tends to rock the lower end of said lever depressed. \Vhen; however, the carriage lug' strikes the stop lug f the spring 60 is .overcome and the tabulator bar moved to the left carrying the lower end of the lever 61 back to the right and releasing the lever 24 whereupon it returns to normal together with other parts operated-by .the tabulator key, the latter of course rising.

In order to provide for release of the tabulator key in an extreme position of the carriage to the left a permanent stop piece 65 is secured on the left hand end of the tabu- If the tabulator key should inadvertently be held down by finger pressure-while the carriage is pushed back to the left, no damage can result for the inclined side of the lug -l0 willac't with a camming effect upon the lugs 47, and the spring 51 will yield to permit the consequent rocking of the tabulator bar. v

It will be observed thatthe provision of scales on both the top and front of the tabulator barand formation of the stop devices to make either scale available, conducesto great convenience in the use of the tabulating mechanism Besides performing the function of lifting the escapement rack the arm 13 also performs thefunction of applying a brake to retardthe movement of the carriage in a tabulating operation. The before-mentioned sleeve 16 is formed with a pinion 67 which'when the arm 13 is thrown upward comes into mesh with the escapement rack so that when the carriage moves to the left in a tabulating operation the sleeve 16 will be rotated. This sleeve has secured to its inner end a ratchet wheel 68 (Fig. 11). and a surrounding collar 69 carries a pawl 70 held by a spring 70 in engagement with said ratchet so that said collar will be rotated with the sleeve wheh the carriage is moving to the left. A coiled spring 71 surrounds the collar. being secured thereto at its inner end. The outer end of said spring is attached to a drum 72 which surrounds it and is loosely journaled upon the sleeve 16. On a suitable bracket of the fran'iework there is secured a brake shoe 73 which extends above said drum and is adapted to be contacted thereby when the arm .13 is raised. The first effect produced in this braking construction by an. operation of the tabulator mechanism is to wind up the spring 71. This alone would suffice to retard the movement of the carriage when that movement is not of any considerable extent, but of course there a limit to the winding of the spring orthe ability of the s carriage to overcome the same and when this limit isreached the drum 16 will be rotated as the carriage continues on its way. The carriage is'then further retarded by the;

friction between the drum and the brake shoe 7 3. s

The before-mentioned spring connection between the fast and loose arms 19 and 24: on shaft-14 provides for the friction drum being yieldingly pressed against the brake,- the spring31 also having a similar eflect, ,so,that a maintained braking pressure is insured Without relying at all upon con-.

. 25 pressed. Near the opposite end of said rock shaft there is secured an arm 77 having at its upper extremity a cam finger 78. The latter engages the front edge of a vertically extending lever 7 9 pivoted at 80 in a swivel piece'81 journaled in the supporting framework. Rocking of the shaft 7 1 causes the cam finger 78 to act against said lever 79' and swing its lower part to the right. The lower end of this lever is jointed at 82 to 3 5 a horizontally disposed lever 83 arranged to swing from side to side; said lever being 1' pivotedat its rear end to the framework as 7 shown at'81 (Fig. 13). At an intermediate point said lever engages a pin 85 on a. sliding shaft 86 extending across beneath,

the character key levers. This shaft carries a series of collars 87 normally out of line with arms 88 of abail Whose cross rod 89 extends under said key levers, said bail being in the present instance the escapement bail. When the tabulator key is depressed and the lever 83 swung to the right, said shaft 86 is shifted to carry its collars 87 under the arms ofsaid bail, thus- ,blocking downward movement of thev character key levers and of course preventing the striking of any type. This same effect is produced when the end of a line is reached in ordinarv writing as will presently be described. The upper .end of the lever 79 is coupled to-an arm 90 of a plate 91 secured to and underlying a sleeve 92 which is arranged to slide to a limited. extent on the front wayrod 93 on which the carriage 8 travels. said sleeve being normally held to the right by a spring 91 in a chamber of the framework surrounding the left hand end of said rod 93 12). On said sleeve there is adiustably mounted'an end stop piece comprising a bodyportion 95 partially embracing the sleeve, the latter"being'1;open along the greater portion of its upper side so that the carriage roller 96 can traversethe rod 93 ,the full extent. The body portion 95 Fig. 18) is recessed to receive a (pawl or dog'97 pivoted therein and engaging a lon g1tud1nally-notched portion 98 of the sleeve 92, a spring 99' serving to enforcesuch en-'-- gagement. Said pawl or dog is formed with a knob or handle 100, and a finger piece 101 is formed on the body portion 95 so that the end stop can be conveniently manipulated by placing the forefinger on this piece 101 and the thumb on the knob 100. The spring 99 has formed integrally with it an index pointer 102 for traversing a scale 103 on the framework. lug 104E (Fig. 16) occupying a spline groove 105 in the sleeve 92 so that said end stop whileadjustable longitudinally of the sleeve does not turn relatively thereto. However the sleeve itself is capable'of a limited rotary movement on the rod 93 for the purpose of sounding an alarm to indicate the approach to the end of a line of writing. The

plate 91 has downwardly-extending arm 106 carrying at its lower end a bell: clapper 107 (Fig. 15) and there is mounted in a'suit able location on the frame of the machinea bell 108 to be struck by said clapper. A spring 110 connects the arm 106' with a stud on the framework holding the said arm rearwardly and the sleeve 92 rocked rearward. The connection between the upper end of the lever 79 and the arm' 90 is such as to permit the rocking of-the plate 91 without affecting said lever. On the front bar of the car-- riage 8 there is pivoted a gravity stop piece 111 (Fig. 12) and on therear side of the body portion 95 of the end stop piece there is formed a beveled lug 112 which said grav-' ity stop piece rides over, rocking the end stop and the sleeve .92 with the effect of throwing forward and then releasing the bell clapper to sound the alarm. The body of the end stop is further formed on its rear side with a lug 113 spaced from the lug 112 and saidwgravity stop piece 111 is adapted to. encounter said lug 113 and thereby shift the end stop and sleeve 92 to the left against the stress of the spring 91, thus rocking the lever 79 and locking the character key levers The end stop piece has a in the same way that they are locked by. de-

pression of the tabulator key as before de. scribed A modified form of end stop is shown in Fig. 19'where only a single manipulating handle is required. The numeral 95' designates the body portion of the end stop which is recessed on the forward side of the sleeve 92 for the reception of a pivoted dog 97 having atail 971", said tail hav ing a cam surfaceengaged'bya complemen- 4 tary edge of a pivoted handle piece 101 A fiat spring 99 secured to thefloody portion 95 bears againstitlw 1:.ba0kof the dog stop (Figs. -22).

. 97.- It will be seen that side pressure on the finger piece 101' will disengage the dog portion 114 partially surrounding. the wayrod 93 which is ratcheted fora distance.

shown at 115 to cooperate with a dog 116 pivotally mounted in. the body portion .114 and having a knob 117 by which to manipulate it. The body portion is formedwith a finger piece. 118 projecting from the end opposlte that where'the knob of the dog projects and this margin stop can thus be manipulated conveniently and effectively as described 'with reference to the end stop.

Engagement of the dog with the-ratchet is enforced by a' flat spring 119 secured to the body portion 114 on the underside thereof I so ' and having formed integral with it an index finger 120, overlying the scale 103. This spring has-also formed integrally'with it a portion 121 extending rearwardlyinto an opening inthe underside of the body portion 114 andthence laterally in a slot of such body portion, this laterally extending.

portion standing on edge and occupying a ongitudinal groove 122.in the underside of the way-rod. The spring thus serves to hold the margin stop yieldmgly in a normal positionwith its front portion lowered. A

stop lug 123 on the upper rear portion of the margin body piece 114 is adapted-to be struck by a contact plate"124 on the carriage frame to limit the movement of the carriage to the right. The margin stop can, however, be tilted against the pressure of the spring so as. to permit the carriage to'be moved farther to the right if occasion should require. The stop lug is beveled on the upper side so that the carriage can 'move back to the left riding over the saidlug against the spring pressure. In this connection it might be stated that the capability of rocking "of the end stop piece with the sleeve on which it is mounted, can be utilized in cases where it may be desired to write beyond the line limit set. The pivotal mounting of the stop piece 111 on the carriage provides for its riding over the lug 113 when thecarriage moves back to the right.

' It will now beseen that the above-described constructions are well calculated to fulfil the various objects primarily, stated, but at the same time itis to be understood that they invention is not necessarily limited to those constructions but may be carried out differently.
